The LDP uses DocBook format for our new documents, and we are trying to get our older documents also converted into DocBook. Unfortunately, DocBook is a very large and complex DTD, so it can be difficult for people to use. We are always looking for ways to make it easier, so more people can help the LDP.
The solution we came upon was inspired by the WikiWikiWeb, thanks to a great suggestion from LDP author Martin Wheeler. I call it WikiText, because it isn't a true Wiki, but it has some of the best features of a true Wiki.
